My acid test: wearing eyeliner to a drinking session... and checking it after sleeping on it. Your body goes through so many changes during a drinking session and I feel like it is a good measure of the abuse your makeup can take over an extended period of time.

Simply glide along the skin to draw. You may shake the pen to activate the metal ball and get more ink out.

PROTIP: The 0.05mm tip allows you to stamp a flick if your hands are feeling a bit unsteady. Simply press the point outward and drag toward the inner corner.

Performance:

This is my top eyeliner! It is probably the only one in my collection that doesn't smudge. EVEN OVERNIGHT. I used to not trust this because it smudged all over my lid. I gave it another chance weeks later and realized I simply wasn't letting it dry long enough! I usually stick my face to the fan for around 10 seconds and once it sets, it's there 'til next morning.

HR Perfect Liquid Eyeliner

is a bit blacker than what I expect from liquid eyeliner. I'm pleasantly surprised because color intensity is usually a weak point for liquid pen liners

however

, it has a shorter lifespan in terms of deeply-black dispensed ink. Kate would take forever to start greying out but I have noticed my HR liner dispensing thinner ink after about two months of inconsistent use. Which isn't to say that it gets used up fast. It is now at least six months since I've opened it and it's still alive and kicking!

The 0.05mm tip is a double edged sword: the fineness lets you stamp a fine flick but if you're not used to stamping and prefer drawing, the too-fine point of contact from tip to skin is almost invisible that you can overdraw connecting lines.

Wear down looks great. It crumbles off in powder form without smearing all over. It doesn't stain all over, which is greaaaat!

Lasting Power:

Overnight, babe.

Edge:

Does not smudge on my low left crease. It has a lot of other great attributes but very few liners can satisfy this condition!

Even though I have a lot of Trusted By Tellie items, I rarely declare something to be Holy Grail material. I can be heavily impressed by something while still feeling this conservative nudge toward uncertainty that many other people may validly disagree.

But given my problematic low crease that constantly throws tantrums at the longest-lasting, bulletproof eyeliners... I am glad to finally find one that shows promise.

Heavy Rotation Perfect Liquid Eyeliner N in Deep Black 01

is the only eyeliner I currently trust. I will use other eyeliners for only two reasons: I know I will be out less than 6 hours and/or I am going for a smudgy look.
